LANDING FLOAT.

Application filed November 30, 1927. Serial No. 236,789.

The present invention relates to landing floats to be used principallyfor the landing of aeroplanes in mid-ocean or on other large bodies ofwater..

Objects of the invention are to provide a float of the above characterwhich will be stable in construction and which will be maintained inproper position for the landing of aeroplanes thereupon and willbeinsured against overturning or sinking due to the stress of the waves orother factors.

Other objects and advantages will appear from the followingspecification and will be set forth in the subjoined claims.

In the drawings which constitute a part of the present specification:-

Figure 1 is a side View of a float built in accordance with theprinciple of my invention.

Figure 2 is a plan view of the same with parts being broken away on line22 of Figure 1 to show the internal structure thereof.

Figure 3 is a view partly in section and 2 as seen looking in thedirection of the arrows on line 3-3 of Figure 2.

Figure 4 is a fragmentary view in section on the line 4l4 of Figure 2.

Referring to the drawings in detail by reference numerals, the samenumerals designating the same parts in all views of .the drawings, 1Odesignates a plurality of floats which may be constructed in dry dockand towed out to sea and then connected together by a superimposedstructure, consisting of longitudinally and transversely extending Ibeams 11 and 12, supported in spaced relation above the floats by meansof seamless steel tubes 13 and connected to 40 gether in any suitablemanner'as by welding or by rivets. Suitable brace members 14; areprovidedbetween the upper I beams 11 and 12 and the tops of the floats,said braces being arranged at an angle of 45 or some such suitable angleto the floats and to the frame comprised of the members '11 and 12. Thegrill work formed by the crossing of the beams 11 and 12 provide asupport for a surfacing of deck plates 15 which is preferably of sheetsteel and with which.

it is contemplatedto cover the entire top of the landing float whichwhen so covered presents a flat surface. Placed upon the steel plates isa surfacing 16 which may be of asphalt or any suitable material designed.ito shed water from the field and to give a proper landing surface foran aeroplane or the like. The superstructure comprising the members 11,12, 13 and 14 is further closed at the top and water rises therein underthe head of floatation. The rocking of the structure by wave action isreduced by the resistance of air against the water in the cups.

The tubes 13 are referably extended downwardly through the tops of thefloats and are connected at their lower ends with transverse I-beams 19extend'gg transversely of the float. Brace members may be providedbetween the upper adjacent edges of the floats and the tops of thetubular members 13 adjacent the ends of said floats as shown in Figure 1of the drawings. The superstructure is made with the sides and endsthereof sloping toward the center in an upwardly direction shown inFigures 1 and 3 and the whole assembly isof such weight that the waterline will be sufficiently above the floats to entirely submerge the sameand insure against the overturning of the float. .The cups 18 asindicated in Figure 3 act to admitpartial rise of water in their lowerends thereby promoting the stability of the device.

Having described my invention, what I claim is 1. A float'of thecharacter described coma plurality of air tight compartments formmemberswith the float compartments, brace ing a partly submerged raft,distributed members connecting said longitudinal and rows of air cellstherein, a superstructure transverse members With the float, and a 1connected thereto and comprising members landing surface for aeroplanesat the top extending longitudinally and transversely of saidsuperstructure.
